MICROCIRCUIT DATA SHEET Original Creation Date: 04/14/97 Last Update Date: 07/08/97 Last Major Revision Date: 04/14/97 CN54F245-X REV 0A0 OCTAL BIDIRECTIONAL TRANSCEIVER WITH TRI-STATE OUTPUTS General Description The F245 contains eight non-inverting bidirectional buffers with TRI-STATE outputs and is intended for bus-oriented applications. Current sinking capability is 24 mA (20 mA Mil) at the A ports and 64 mA (48 mA Mil) at the B ports. The Transmit/Receive (T/R) input determines the direction of data flow through the bidirectional transceiver. Transmit (active HIGH) enables data from A ports to B ports; Receive (active LOW) enables data from B ports to A ports. The Output Enable input, when HIGH, disables both A and B ports by placing them in a HIGH Z condition.
